Question about Acer Aspire T650 (AST650UC3601) PC Desktop
Acer Aspire T650-997Z whit two slots for memory 2X512MB-Nanya NT512T64U88A0BY-37 DDR2 DIMM.After trying to change whit 2X1GB Transcend JM667QLG 240pin DDR2 DIMM my PC ,runing WinXP boot BIOS,but going just to screen when asking me how to start Windows-normaly or in safe mode and after i choose normaly, blink blue screen and follows reboot. I try to run it whit old memory module and it works.Both Transcend moduls are working but only in combination whit the old one-in the first slot 512MB Nanya and in second slot each of Transcends moduls.I'm wondering why this happening,and how to solve it?
The read speed of your new memory is not compatible with your motherboard. It is a higher rate than allowed. The reason why it works when you have one of your old chips installed is because your PC will automatically drop the higher rate chip down to the one that is working. The reason it does not drop both new chips down to a suitable rate is because it has nothing to guide it like your compatible chip does. Always check the MHz on RAM chips and compare that with the acceptable rates listed on your motherboard specs. The good news is you can probably sell those chips and have money left over when you find upgraded compatible memory that is sure to be cheaper since it is slower.

SOURCE: memory installation
Most likely it has to do with your chipset. You might also be trying to run the RAM in dual-channel mode. Some systems are extremely finicky in dual-channel. Next time you boot, try looking in the BIOS to check if dual-channel is enabled or not. If it is, try disabling it and putting the chips back in. You can also go to your motherboard manufacturer's website and check for BIOS updates, as they tend to help with things like this.

SOURCE: Ram upgrade capability
Simply, yes you can. just open the case and put in the new boards. you can buy higher spec. memory(as long as the pins are the same number)
I.E. ddr-sdram boards will fit and as long as the speed is the same (132.8 Mhz) or higher.
I changed from 133Mhz to 333Mhz and the performance was much improved.
The PC3200 is the important bit, should be the same.
after you change the memory ,try running disc clean up in "start, all programs, accessories, disc clean up" this will also speed things up as well as de-fragmennting your drive(s)

SOURCE: cannot format c:
if you want to format it you have to reinstall the os . Actually all information of the os is sitting in c drive ... in running time of windows you can't format the c drive .....
To format and reinstall the os get a windows(XP,vista,98) botable cd ...boot from cd ... it will start the setup...... in middle of setup it will ask for the format ......

Most likely the motherboard does not take more than 1 Gb of RAM. If so then you will have to do with 1 GB only. The new RAM is fine as it works alone.
